Adding intermittent vibration to varied-intensity work intervals: no extra benefit (2022)
Journal Article
Bossi, A. H., Mesquida, C., Hopker, J., & Rønnestad, B. (2023). Adding intermittent vibration to varied-intensity work intervals: no extra benefit. International Journal of Sports Medicine, 44(02), 126-132. https://doi.org/10.1055/a-1812-7600

Varied-intensity work intervals have been shown to induce higher fractions of maximal oxygen uptake during high-intensity interval training compared with constant-intensity work intervals. We assessed whether varied-intensity work intervals combined... Read More about Adding intermittent vibration to varied-intensity work intervals: no extra benefit.

Optimizing Interval Training Through Power-Output Variation Within the Work Intervals (2020)
Journal Article

Purpose: Maximal oxygen uptake (˙VO2max) is a key determinant of endurance performance. Therefore, devising high-intensity interval training (HIIT) that maximizes stress of the oxygen-transport and -utilization systems may be important to stimulate f...
